Summary

Compares two strings.

Pascal

 function StrCompare(const S1: string; const S2: string; CaseSensitive: Boolean = False): SizeInt;
function StrCompare(const S1: AnsiString; const S2: AnsiString; CaseSensitive: Boolean = False): SizeInt;

Parameters

Parameters	Description
const S1: string	First string to compare.
const S2: string	Second string to compare.

Return Value

StrCompare returns 0 if the two strings match or the number of different characters in case of a mismatch.

Description

StrCompare implements a case-insensitive comparison between the two supplied strings. If the two strings match the function returns 0 otherwise it returns the number of different characters. If the supplied strings are of equal length but are not identical the function returns the difference of the first mismatched character. The table below demonstrates this:

S1	S2	Result
jedi	jedi	0
jedi	je	2
di	jedi	-2
project jedi	jedi	8
jedi	project jedi	-8
jedi	judi	Ord('e') - Ord('u')
JEDI	Judi	Ord(LowerCase('E')) - Ord('u')
